Why does temperature remain low in polar regions despite the long dura...
Reasons for low temperature in polar regions despite long duration of sunshine in summers:
Reasons for this phenomenon include:
The sun rays are too oblique:
- Due to the tilt of the Earth's axis, the polar regions receive sunlight at a very low angle during summers. This results in less direct heating and lower temperatures despite the long duration of sunlight.
Most of the sunshine is absorbed by the ice caps:
- The polar regions are covered with ice caps that have a high albedo, meaning they reflect a significant amount of sunlight back into space. This reduces the amount of energy absorbed by the surface, leading to lower temperatures.
The snow reflects much of the sunshine:
- Snow also has a high albedo, reflecting a large portion of the sunlight that falls on it. This further contributes to the cooling effect in polar regions.
Combined effect of oblique sun rays and reflective surfaces:
- The combination of oblique sun rays and the reflective surfaces of ice caps and snow results in a significant portion of the sunlight being either reflected or not absorbed, leading to low temperatures despite the long hours of daylight.
Therefore, the low temperature in polar regions during summers can be attributed to the oblique angle of sunlight, as well as the reflective nature of ice caps and snow, which result in less heat being absorbed by the surface.

Despite the long duration of sunshine in summers, when the sun does not set, the temperature remains low as the sun rays are too oblique, with much of it getting reflected by the snow, and the remaining being used up in melting the ice.
